For effortlessness, the framework is improved to a propeller, a solitary shaft, diary bearing and a push bearing. As the vessel travels through the sea, a wake is produced. This non-uniform wake field is the inflow to the propeller. The power produced by the propeller is additionally non-uniform.&nbsp; The impetus arrangement of a marine vessel is the principle supporter of commotion emanated from the vessel. It is along these lines important to diminish the commotion sent from the propeller into the sea and consequently the vibration that is created by the propeller that is thus communicated into the body. The inspiration for lessening commotion and vibration remembers diminishing mechanical wear for segments, expanding secrecy limit of military vessels, improving traveler and group solace, and decreasing the effect on marine conditions. The point of this theory is to dissect the shaky power created by the propeller, the power transmission ways, and techniques to quantify the power transmission through the push bearing continuously.</p> Salsabil karim Mohammed Copyright (c) 2021 Journal Port Science Research Thu, 11 Nov 2021 00:00:00 +0300 Facial Expression Recognition from Video Sequence Using Self Organizing Feature Map <p>Automatic analysis of facial expressions is rapidly becoming an area of intense interest in computer vision and artificial intelligence research communities. In this paper an approach is presented for facial expression recognition of the six basic prototype expressions (i.e., joy, surprise, anger, sadness, fear, and disgust) based on Facial Action Coding System (FACS). The approach utilizes the topological ordering patterns produced by Kohonen Self Organizing Map, in which implemented on expression image sequence for each prototype facial expression. The map will compute the topological relationship between the particular expression sequences, starting from the neutral expression to peak. This method tried to find a topological ordering pattern (shape) for each expression; it will not require any pre-processing tedious work such as normalization. The only requirement is that, image background must be kept constant, also with non-rigid head motion.&nbsp; The feature extraction phase had been performed by this method, while the classification phase done by especially designed procedures for shape and direction finding to recognize the pattern of the shape, thereafter the type of the expression also backpropagation neural network is implemented for the classification task. An average recognition rate of 88.7% was achieved for six basic expressions, where different databases had been used for the test of the method.</p> Walid Amin Mahmoud, Jane Jaleel Stephan, Anmar Abdel Wahab Razzak Razzak Copyright (c) 2021 Journal Port Science Research Thu, 10 Jun 2021 00:00:00 +0300 Big Data Visualization by MapReduce for Discovering the Relationship Between Pollutant Gases <p>Big data mining and pollution are extremely important issues in todays. An innovative method in this study was used for visually discovering the relationship between pollutant gases by MapReduce. One dimensional, two-dimensional, and three-dimensional visualization used to visualize the data, that was processed as an hourly reading for one year from an air quality monitoring station to study the behaviors of pollutant gases distribution, and to show graphically the distribution of one, two, or three gases. The number of readings used in this paper are 8760 hourly readings for each of the five pollutant gases under this study. Pearson correlation used to explore numerically the correlation between the pollutant gases, and eta factor used to evaluate the effect of one gas on the other pollutant gases. We found out by both methods, visually and numerically the same facts that related between the pollutant gasses. The ozone has a moderate negative correlation of value -0.622 with nitrogen dioxide, and weak negative correlation of value -0.248 with carbon monoxide, and -0.155 with carbon dioxide. Ozone has approximately no correlation of value .060 with silver dioxide. The carbon monoxide has moderate positive correlation of value 0.364 with carbon dioxide. The eta factor between ozone and nitrogen dioxide is very weak of values 0.292, and 0.009 with Sulphur dioxide, this proved an important fact that the ozone, nitrogen dioxide, and Sulphur dioxide sources are different. The study recommends that each country must analysis visually and numerical the big data that was collected yearly from the monitoring stations to control the pollution gases especially near the large industrial factories.</p> Yas A.

It consists of Photovoltaic, Wind turbine, Hybrid Energy Storage System (HESS). The HESS system consist of Batteries, Supper capacitors, with chargers. The proposed system used real record of weather pattern and load conditions for Al-Mahmoudiya Hospital. The variable sources are changing with different weather conditions. Being important energy sources for generating electricity directly from the sun. In order to generate electrical energy that is sustainable and reliable, highly efficient, low cost, and continuous. It can provide maximum power use. The absence of winds in most regions of Iraq permanently led to the use of such a type of renewable energy (RE) system called solar updraft tower (SUT). The wind turbine can be fixed inside the chimney of the SUT, to make the turbine run smoothly and continuously. Each of the HRES parts is controlled by a converter specific to each source due to the nature of the nonlinear source work. In this paper, the main sources of energy are photovoltaic panels and SUT. Finally, MATLAB program using real recorded data, the system work at a high efficiency of 98%. So the simulation results show the HRES system have excellent results and fast tracking to supply the load demand.</p> Fadhil Abbas Mahdi Al-Qrimli Copyright (c) 2021 Journal Port Science Research Mon, 15 Nov 2021 00:00:00 +0300 Design and implementation of irrigation prototype system based GSM <p>Smart farming is one of the keys for future agriculture because it is a management to use modern technology for increasing the quality and quantity of the agriculture. And because of the planet quality depend on the amount of water and the characteristics of soil, it is necessary to study the soil using the soil moisture sensor to investigate whether the soil is dry or wet, also to consider the challenges that could be faced in agricultural environment by maintain the soil and the planets irrigated without extra usage of water. In this paper, a prototype irrigation system uses Arduino Uno microcontroller which is programmed in C++ language to sense the degree of moisture by using soil moisture sensor. According to moisture sensor readings, when the moisture sensor above 1000, Arduino triggers to supply the water by using 5V mini water pump and stop when the soil moisture sensor reading reaches below 400. GSM technology enables the user to be notified in any changes happening in agricultural area by sending SMS (Short Message Service). Whenever the soil become wet or dry and the mini water pump switched on or off, a message delivered to user’s cellular phone indicating the condition of the soil and the action of water pump. In that capacity, this prototype will reduce the time for the user by monitoring remotely without going to his land, and also to reduce the usage of water by allow the water pump to flow the water for limited time until the moisture degree raise again.</p> Muhammad Fahim.
